7 bool "Watchdog Timer Support"
9 If you say Y here (and to one of the following options) and create a
10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back
15 on-line as fast as possible after a lock-up. There's both a watchdog
16 implementation entirely in software (which can sometimes fail to
17 reboot the machine) and a driver for hardware watchdog boards, which
18 are more robust and can also keep track of the temperature inside
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
22 The watchdog is usually used together with the watchdog daemon
23 which is available from
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process
33 bool "WatchDog Timer Driver Core"
35 Say Y here if you want to use the new watchdog timer driver core.
36 This driver provides a framework for all watchdog timer drivers
37 and gives them the /dev/watchdog interface (and later also the
40 config WATCHDOG_NOWAYOUT
41 bool "Disable watchdog shutdown on close"
43 The default watchdog behaviour (which you get if you say N here) is
44 to stop the timer if the process managing it closes the file
45 /dev/watchdog. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
49 config WATCHDOG_HANDLE_BOOT_ENABLED
50 bool "Update boot-enabled watchdog until userspace takes over"
53 The default watchdog behaviour (which you get if you say Y here) is
54 to ping watchdog devices that were enabled before the driver has
55 been loaded until control is taken over from userspace using the
56 /dev/watchdog file. If you say N here, the kernel will not update
57 the watchdog on its own. Thus if your userspace does not start fast
58 enough your device will reboot.
61 bool "Read different watchdog information through sysfs"
63 Say Y here if you want to enable watchdog device status read through

86 bool "Software watchdog pretimeout governor support"
87 depends on SOFT_WATCHDOG && WATCHDOG_PRETIMEOUT_GOV
89 Enable this if you want to use pretimeout governors with the software
90 watchdog. Be aware that governors might affect the watchdog because it
91 is purely software, e.g. the panic governor will stall it!

262 ARM SBSA Generic Watchdog has two stage timeouts:
263 the first signal (WS0) is for alerting the system by interrupt,
264 the second one (WS1) is a real hardware reset.

267 This driver can operate ARM SBSA Generic Watchdog as a single stage
268 or a two stages watchdog, it depends on the module parameter "action".

334 here if you wish to use this. Alternatively say M to compile the
335 driver as a module, which will be called wdt285.

376 which doesn't reset any peripherals. There are circumstances
377 where the watchdog will fail to reset the board correctly
378 (e.g., if the boot ROM is in an unreadable state).
380 Say N if you are unsure.

477 affect both cores and the peripherals of the IOP. The ATU-X
478 and/or ATUe configuration registers will remain intact, but if
479 operating as an Root Complex and/or Central Resource, the PCI-X
